T0 1 /ZZ whom t may concern:

Be it known that I, EvENcE OOPPE, industrial, a subject of the King of Belgium, and a resident of `7l Boulevard dOnderlecht, Brussels,-Belgium, have invented a certain new Coke-Oven (system Evence Coppee) with or without Recovery of the By f Products, of which the following is a specification.

The object of my invention is to provide an oven in which the gases may be introduced into the lower parts thereof and principally under the bottom of the oven-chamber, so that the greatest heat may be produced in these lower parts and the heat in the upper parts will not be great enough to decompose the light oils which are evolved from the coal in the oven. lets for the gases and air, so as to have uniform heat in the middle and at the ends of the oven. Further, I aim to provide means for dividing and controlling the draft in the flues of the oven and to separately regulate the draft of the gases and of the ai-r introduced at the front and at the back of the oven into these flues.

In the accompanying drawings, Figure l is a vertical longitudinal section through the iiuechambers. Fig. 2 is a similar view through the oven-chamber.A Fig. 3 is a partial transverse sectional view on line 3 3 of Figs. 1 and 27 showing one oven-chamber complete and one-half portion of an oven-chamber on each side thereof with the intermediate flues. Fig. 4: is a partial transverse sectional view on line 4 l of Figs. l and 2, showing one-half of two oven-chambers with a flue between. Fig. 5 is a partial sectional view on line 5 5 of Figs. l and 2, similar to Fig. 3. Fig. (i is a partial vsectional view similar'to Fig-3 on line 6 6 of- Figs. l and 2. Fig. 7 is a Vpartial cross-sec tional view, similar to Fig. 4., on lines?v 7 of Figs. 1 and 2. Fig. 8 is a partial or detail horizontal sectional view on line 8 8 oflFig. 2. Fig. 9 is a horizontal sectional view on the line 9 .9of Fig. 2. Fig. l0 is a similar view on line l0 l0 of Fig. 2.

The gases evolved from the coals in the oven-chambers pass from the upper part of the oven through six openings k into the four chambers jp, whence they descend by Way of four openings Zand two openingsj, passing' for that purpose through the horizontal ports I also aim to distribute the inllo", Figs. l and 3. The gases descending by way of two openings Z, arranged at the front end of the furnace, continue their descent through four'vertical fines n o q fr to a chamberf, Figs. l, 3, and 9, and from this chamber ,the gases pass by the opening c into chamber S, which is, as Ashown in Figs. 2 and3, located beneath the floor of the oven. The floor of the oven is heatedby these gases, and said gases then ascend by four vertical lines d elf g.' At the back of the joven the gases issuing from the two openings Z descend by four vertical flues n o' q fr into a chamber w. This chamber is divided into a lower and an upper part, and from the upper part the gases pass by way of the valve d into the lower part of this chamtical ilues d' ef g', similar to those before described. The gases issuing from the two openings j at the center of the oven descend 1 on each side of ya central partition J, which separates the lues into two series, one .at the front and one at the backof the oven, said lines being located in the walls between the oven-chambers and comprising the vertical flues already mentioned and also the descends in g vertical iiues s t u and s t u. The gases descending through the tluej onthe rear side of thepartition .I mix with the gases ascending through they fines df ef g and then descend through verticalflues s t u into a chamber R, thus passing under the rear part of the oven-Hoor, so as to heat the same, the chamber VR discharging into a flue h2 under the rear floor of the oven-chamber, which iiue also aids in the heating action. The gases issuing from the fiuej on the front side of p the partition .I mix with the gases risingfrom the flues d e f g,'and the mixed gases then descend through the flues s t fea-Figs. l and 9, into a horizontal iue b at tthe rear of the oven and extending parallel with the flue b2, before mentioned. The gases passing through the ilues b2 and t proceed to the fluesfu, which are provided with valves, and thence into the collecting-channel C and to the vertical chimney. The two valves in thel flues U are intended to regulate the draft in said fines, one serving for the fluids discharged from the front portion of the oven-fines and the other serving to regulate the draft from the other series of oven-fines. By the arrangement deber, and thence the gases rise through the ver-4 TOO scribed the heat is uniformly distributed throughout the oven.

The foregoing description relates to an oven in which no provision is made for the recovery of the by-products, and I will now describe the same oven adapted to work with recovery of said by-products.

As shown in Fig. 2, openings k lead from the top of the oven-chamber, said openings being controlled by valves. These valves prevent the passage of the gases from the oven-chambers to the lues in the walls of the oven. Pipes T T extend from the upper part of the oven to conduits U, arranged above the oven, through which the gases are conveyed to a condensing apparatus, and from this apparatus the gases return by conduits fc, Fig. l, placed above the oven. From these distributing-pipe branches extend, so as to discharge the gases into the lues at various points, as shown at a. bj t', suitable stop-cocks being arranged to regulate the quantity of gas discharged.

First action: The introduction of a small portion of gas, as well as of the air necessary for its combustion, is effected at ct. In the front half of the oven the gases descend through the four vertical fines n o q r and pass by way of opening c' into the chamber S under the floor of the oven, where these gases Imeet the gases introduced directly into the chamber S by the opening t'. After having taken a sufficient quantity of air, which is introduced by flue m, the mixture ascends through the verticaltlues d e f g to the space V, located above the vertical dues. I'Iere the gases meet the fresh supply introduced through the openingj, to which airis supplied by the air-inlet d. descends through the vertical fines s t u into the flue b', extending under the iioor of the oven, and thence through the liuc fu into the collecting-channel C. At the rear half of the oven the gases introduced at a descend by the vertical flues fn. o q r' into the upper part of the chamberw, which is divided by a horizontal partition. From the upper part of the chamber the gases pass by the valveopening d into the lower part, where they meet the gases introduced at t' into the lower part. The gaseous mixture ascends through the fines d e f g to the space V, where a further mixture is effected with the gases inl troduced through the port j', and the final mixture then passes through the iues s t u into the chamber R under the Hoor of the oven and thence through the flue b under the floor of the oven to the flue e and thence to the collecting-channel.

Second action: In this second operation the partitions c, Fig. 1, which divide the descending ues n o q r and n o q r' from the ascending flues d efg and d ef g', are removed. In front of the oven the introduction of the gases and air for combustion takes place at b into the chamberf, from The gaseous mixture then,

whence the gases ascend from fines n o q r to the space above said lines, where a mixture is effected with the gases rising through the ues d efg, which gases have been introduced at t, Fig. 2, at the front of the oven. The gases introduced at t' ascend through the vertical flues d e f g after having received the necessary air for their combustion through the iiue m. The mixture of gases from the points of supply b and t' now meet the gases introduced at j, which latter gases have been supplied with air for combustion through the air-inlet d. This final mixture now descends bythe vertical flues s t u, Figs. 1, 2, and 9, below the iioor of the oven, from whence they pass through the horizontal'iiue b to the collecting-channel C.

At the rear of the oven the gases are introduced at b below the vertical iues and into the upper part of the chamber w, the valve being held up at the opening d. The gases ascend through the flues op q r'. The gases introduced at t', with air for their combustion, pass into the lower part of the chamber tu, and ascend into the flues d ef g to mix with the gases introduced at b in the space V. The mixture of gases supplied at the points b and t' at the rear of the oven next meet the mixture of gases and air introduced atj', and this final mixture then descends through the vertical iiues s t u to the chamber R and thence by way of iiue b2 to the collecting-channel.

To sum up, I consider as new and claim by patent-right* In combination, in a coke-oven, the ovencha'mber, the openings 7c leading from the upper part thereof and at diiferent points along the oven, the series of chambers p with which the openings 7c connect, the openings Z, Z, near the front and rear of the oven leading from the end chambers p and the openings j, j, leading from the middle chambers p, said openings Z and j leading to the ilues, which comprise the vertical series of iiues for the ascending and descending currents, said flues being distributed along the oven from front to rear and adapted to heat the front, rear and middle of the oven, the passages under the sole of the oven and with which the vertical flues connect, means for introducing gas into the lower passages so that the greatest heat may be generated in the lower parts of the oven, a series of exhaust-fines having dampers and communicating with the ilues at the dierent parts along the oven, the dampers for the open-v ings 7c and a condensing apparatus connected with the oven, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
